BATTERY TERMINAL CONNECTER Filed Jan 25, 1931 [ow/W0 1f .SHk/ 4E ATTO RN EYS Patented Mar. 13, 1934 UNITED STATES PATENT OFFICE 1 Claims.

This invention relates to battery terminal connecters such as are employed on storage bat teries.

Heretofore considerable difficulty has been experienced with the removal of storage battery terminal post connecters due to the fact that the same become corroded. In attempting to remove such connecters the prying of the same upwardly with a screw driver or the forcing of the nut with a wrench frequently results in injury to the battery, the tool slipping and breaking the top of the battery or the terminal post being pulled loose, etc.

The purpose of the present invention is to provide a connecter for battery terminal posts which may be removed with ease by means of a simple tool of the character of a pair of tongs or the like without danger of injury to the battery.

More particularly the invention has for its object the provision of a battery terminal connecter with hook formations thereon so arranged that a tool such as tongs may be readily engaged therewith to lift the connecter off a terminal post.

The foregoing and other objects of the invention are attained in the terminal connecter and by the use of the tool illustrated in the accompanying drawing and described below. It is to be understood that the invention is not limited to the specific form thereof shown and described.

Of the accompanying drawing,

Figure 1 is an elevation, partly in section, on line 1-1 of Figure 2 of the improved connecter shown mounted upon a storage battery terminal post with the removing tool associated therewith for removing the same;

Figure 2 is a plan of the improved connecter; and

Figure 3 is a side elevation thereof on the left side of Figure 2.

Referring to the drawing, the numeral 10 designates a storage battery having a terminal post 11 upon which the improved connecter is mounted.

The improved connecter is of the standard type at present in universal use including clamping jaws 12 and 13 adapted to be tightened on the post 11 by a bolt 14 extending through the jaws with a nut 15 threaded thereon, the jaws being attached to a socket member 16 to which the usual lead cable (not shown) is attached.

The present invention consists in providing said connecter with downwardly directed hook formations 17 and 18 having downwardly and outwardly curved upper surfaces 1'7 and 18 and under surfaces or shoulders 1'7 and 18 elevated sufiiciently above the bottom of the connecter, so that when the connecter is seated at the base of the post as shown, a tool may be engaged under said shoulders.

The preferred tool comprises a pair of tongs 19, 19 pivoted upon a support 20 through which a screw 21 is threaded so that the screw may be engaged with the top of the post 11 as shown exerting a downward pressure upon the post and a lifting force upon the tongs.

The tongs 19 are preferably yieldingly urged toward each other to positions at which'they are spaced a distance approximating the width of a battery post, pins 19 limiting the lower positions of the tongs, the top surfaces 1'? and 18 of the hooks are adapted to spread the jaws when the tool is pressed downwardly thereover.

The jaw 1'7 is preferably so arranged, as indicated in Figure 3, as to prevent rotation of the 7 bolt 14 by engagement with a side face on the head 14= of the bolt.

To remove the connecter it is not necessary to first loosen the bolt 14, the tool being merely engaged with the post and the connecter as shown in Figure 1 and screw 21'actuated to lift the connecter off the post.

Modifications of the invention may be resorted to without departing from the spirit thereof or the scope of the appended claim.

What is claimed is:-

A battery terminal connecter comprising a member for embracing a battery post and having spaced jaws with a bolt extending therethrough to clamp said jaws upon a battery terminal, said connecter having a hook-like formation on each side thereof, said formations having shoulders on the under sides thereof spaced from the bottom of the connecter and under which a tool is engageable when said connecter is seated upon a battery terminal, one of said formations being arranged to be engaged by the head of said bolt to hold the bolt from turning.
